Moist And Rich Guinness Chocolate Cake
There was a birthday in our house recently. And in my family, you always make a homemade birthday cake. None of this bakery-bought fancy cake stuff. I stumbled upon this Guinness Chocolate Cake a few months ago. I’m not a Guinness drinker, but I had some on hand for another recipe, so why not try it? Well, it’s the most moist, rich chocolate cake recipe I’ve found.
There’s something undeniably special about a rich, moist chocolate cake. But when you add Guinness to the mix, it transforms into something extraordinary. This Guinness chocolate cake isn’t just any chocolate cake—it’s incredibly deep in flavor, velvety in texture, and has a subtle malty richness that takes it to the next level.
The recipe I used is based on one I found on the NY Times Cooking website. But the original was from Nigella Lawson, link here. They are slightly different, so I made it closer to the NY Times version, using a lot less butter.
Why Add Guinness to Cake?
If you’ve never baked with Guinness before, you might be wondering what role it plays in this cake. The answer is simple—Guinness enhances both the flavor and texture in ways that make this cake unforgettable.
- Flavor Boost: The stout beer adds a subtle roasted coffee and caramel note, which pairs beautifully with the cocoa powder, making the chocolate flavor more intense and complex.
- Moisture & Tender Crumb: The carbonation in Guinness helps create a light, tender cake, while its natural bitterness balances out the sweetness, resulting in a perfectly balanced bite.
- Richness Without Overpowering: Unlike some alcohol-based desserts, the beer’s flavor doesn’t dominate. Instead, it melds seamlessly with the chocolate, leaving just a hint of depth in the background.
The Secret to the Best Guinness Chocolate Cake
Using high-quality cocoa powder is key to getting the richest chocolate flavor. Pairing it with Guinness Stout enhances the deep cocoa notes, making the cake even more decadent. This recipe also calls for sour cream, which adds extra moisture and a slight tang, preventing the cake from being too sweet.
Ingredients You’ll Need to Make A Guinness Chocolate Cake
- Guinness Stout – The star ingredient, adding depth and richness
- Unsalted butter – Helps create a smooth, velvety batter
- Cocoa powder – Use high-quality, unsweetened cocoa for intense chocolate flavor
- Sugar – Balances the bitterness from the stout and cocoa
- Sour cream – Adds moisture and a slight tang
- Eggs – Give structure and stability to the cake
- All-purpose flour – Provides the right texture and structure
- Baking soda – Helps the cake rise perfectly
Step-By-Step Instructions
- Prepare the Batter: Heat Guinness and butter together until melted, then whisk in the cocoa powder and sugar until smooth.
- Mix the Wet Ingredients: In a separate bowl, whisk together eggs, vanilla and sour cream until well combined. Slowly mix in the Guinness mixture.
- Incorporate the Dry Ingredients: Combine the flour and baking soda, then gently fold into the wet ingredients. Be careful not to overmix.
- Bake to Perfection: Pour the batter into a prepared cake pan and bake until a toothpick inserted in the center comes out clean. The cake should be moist but set.
- Cream Cheese Frosting: Beat room-temperature cream cheese with powdered sugar and a touch of heavy cream.
Tips For Success
- It’s easy to make as a layer cake or a larger single layer, you can divide it between two 8-inch pans. Just check it for doneness early. I’ve found that the single layer does take closer to the 1-hour mark to cook. And the 2 layers took me closer to 40 minutes.
- Let the cake sit overnight before serving. The flavors develop even more, creating an even richer and more indulgent dessert.
- You can easily change up the frosting for a buttercream, either chocolate or vanilla.

Chocolate Guinness Cake
Ingredients
Cake
- 1 cup Guinness
- 10 tablespoons unsalted butter plus additional for buttering the pans
- ¾ cup unsweetened cocoa
- 2 cups superfine sugar
- ⅔ cup sour cream
- 2 large eggs
- 1 tablespoon vanilla extract
- 2 cups all-purpose flour
- 2½ teaspoons baking soda
Frosting
- 8 ounces cream cheese
- 1¼ cups confectioners’ sugar
- ⅛ cup heavy cream
Instructions
- Preheat the oven to 350ºF, butter, and line a 9-inch springform pan. It can also be made this as a layer cake with 2 buttered 8-inch pans and lining the bottom with parchment.
- Combine Guinness and butter in a pan and heat on medium-low heat, until the butter is melted. Remove from the heat.
- Whisk the cocoa and sugar together in a small bowl and add to the pan with the Guinness and butter mixture. Combine.
- Mix the sour cream with the eggs and vanilla and combine thoroughly. Add to the Guinness, butter, cocoa, and sugar mixture.
- Combine the flour and baking soda. Add to the Guinness mixture and whisk until smooth.
- Pour the cake batter into the greased and lined tin and bake for 45 minutes to an hour. If you are making it a layer cake, reduce the cooking time slightly and check for doneness at about 35 minutes. Leave to cool completely on a cooling rack. Since it is quite a moist cake, cool in the pan.
- Once the cake has cooled, prepare the frosting. Lightly whip the cream cheese until smooth, add the confectioners’ sugar, and then beat to combine.
- Add the heavy cream and beat until you have a spreadable consistency. If the frosting is too thin, add a little additional confectioners' sugar to thicken a bit.
